The news on immigration has been almost completely consumed lately by the arrival of tens of thousands of Central American children, many unaccompanied, at the U.S. border.  These children, fleeing violence, poverty, cartels and gangs, undertake huge risks to find refuge in the U.S. and the situation poses an immense humanitarian challenge for U.S. authorities.  Rightly so, U.S. law provides special protections for children arriving at U.S. borders.  These protections, however, are costly, particularly with the numbers of children arriving.  It is truly a refugee situation that Americans are more accustomed to reading about than experiencing at our own border.
